[Introduction]：NB144ES is an industrial-grade 4-way serial port server that supports POE power supply. The shell adopts three-proof coating, which is Anti-Fungal, Anti-Humidity, and Anti-Salt Spray. It integrates the TCP/IP protocol stack inside, which can realize two-way transparent transmission of data from the 4-way serial port to the Ethernet port.
